“Potential Contribution of the Piezoelectric Effect to the Creation of Gold Deposits”

### The Formation of Gold Deposits: A Hypothesis based on Earthquakes and Quartz Crystals

Gold has been revered for its allure, scarcity, and resistance to oxidation. Its worth arises not merely from human appreciation but also from its distinct chemical characteristics. Gold is extremely unreactive, meaning it does not readily bond with other elements, and it has minimal solubility in most solvents. These traits complicate its extraction from other substances, which is why a significant portion of the gold we extract originates from deposits where it exists in sizable, unblemished chunks. This leads to an intriguing question: If gold is so challenging to extract, how do natural processes manage to produce such extensive reserves of it?

A team of Australian scientists has recently put forth an exciting hypothesis that might answer this query. They propose that the emergence of substantial gold deposits could be associated with the piezoelectric effect in quartz crystals, instigated by the pressure from tectonic movements, such as earthquakes. This theory not only provides a possible explanation for gold deposit formation but also correlates several apparently unrelated geological phenomena.

#### The Influence of Orogeny on Gold Formation

Around 75% of gold extracted by humanity arises from orogenic gold deposits. Orogeny pertains to the tectonic activities that form mountains, and these gold deposits materialize in the fractures where two rock masses are sliding against each other. These zones are often abundant in heated hydrothermal fluids, which can dissolve gold, albeit in very low concentrations—typically under a milligram per liter of water.

Notably, these gold deposits are nearly always linked to quartz, a mineral that develops crystalline structures of silicon dioxide. This correlation between quartz and gold is not mere coincidence and forms the foundation of the new hypothesis.

#### The Piezoelectric Effect in Quartz

Quartz stands out among common minerals due to its piezoelectric nature, meaning it produces an electric charge when subjected to mechanical stress. The piezoelectric effect occurs because quartz crystals possess a lack of symmetry (they are non-centrosymmetric). When these crystals are deformed under pressure, a disruption in their internal electric structure results in an electrical potential, or voltage, across the crystal. This voltage is directly proportional to the applied mechanical force.

Quartz is also an insulator, which means the electric charge it generates does not dissipate easily. However, this charge can be neutralized by the transfer of electrons to or from materials that interact with the quartz, including fluids. This electron transfer can instigate redox (reduction/oxidation) reactions in nearby fluids, potentially causing dissolved ions to precipitate and deposit on the quartz.

#### A Self-Reinforcing Mechanism

When a tiny metal deposit, such as gold, develops on the surface of quartz, it can enhance additional electron exchange with the adjoining fluid, resulting in further metal accumulation at the same site. This mechanism could be self-reinforcing, as the initial deposit reduces the concentration of metal ions in the adjacent fluid, promoting additional ions to migrate to the deposition site. This implies that the fluid itself doesn’t need to continuously pass over the same area for the deposit to enlarge.

The hypothesis also necessitates a source of strain to initiate the piezoelectric effect. As these processes occur in active fault zones, where tectonic strain is prevalent, this condition is readily satisfied.

#### Experimental Validation

Investigating this hypothesis in active fault zones would be notably difficult due to their inaccessibility and the gradual nature of these processes. Nevertheless, the researchers executed a more straightforward experiment to explore the concept. They immersed quartz crystals in a solution containing gold, either as gold chloride ions or as suspended gold nanoparticles. The crystals experienced strain at a frequency comparable to that generated by minor earthquakes, and the experiment lasted for an hour.

The findings were revealing. Small gold deposits appeared on the pure quartz crystals, irrespective of whether the gold was in dissolved form or as nanoparticles. In the case of naturally occurring quartz, which already bore minute gold deposits, the new gold was deposited on the pre-existing sites instead of forming new ones.

The researchers also observed that much of the quartz in natural deposits is disordered, comprising numerous small crystals aligned randomly. In such disordered material, the piezoelectric effect of individual crystals tends to negate, indicating that gold will preferentially aggregate on single crystals. This insight aids in explaining why gold is frequently discovered in substantial chunks within these deposits.

#### Conclusion and Future Prospects

This hypothesis is intriguing as it accounts for a previously enigmatic phenomenon through established scientific principles. The experimental evidence supports the notion that the piezoelectric effect in quartz could significantly influence the creation of extensive gold deposits. However, additional research is required to measure the rate of gold deposition through this method and to compare these experimental findings with natural gold deposits.

As we advance our comprehension of these processes, we may reveal new insights into the geological conditions that foster the formation of gold deposits, potentially

Starlink Notifies Brazil That It Will Not Restrict X Platform Unless Authorities Release Its Assets

### Elon Musk’s Starlink Resists Brazilian Court Directive to Restrict X Platform During Ongoing Legal Dispute

In a marked confrontation between Elon Musk’s Starlink and the Brazilian judiciary, the satellite internet service has declined to adhere to a court directive ordering the restriction of Musk’s social media outlet, X (previously known as Twitter), within Brazil. This opposition arises amidst intensifying friction between the tech entrepreneur and Brazil’s Supreme Court, particularly involving Judge Alexandre de Moraes, a significant authority recognized for his strict decisions regarding free expression and social media oversight.

#### Origins of the Dispute

The strife dates back to April 2024, when Musk publicly declared his intention to ignore a Brazilian court ruling that required the suspension of multiple X accounts accused of disseminating falsehoods. Numerous accounts were associated with advocates of Brazil’s former right-wing leader, Jair Bolsonaro. The court’s ruling was part of a wider initiative to reduce the dissemination of misinformation, a strategy that Musk, a self-identified “free speech absolutist,” strongly contested.

Musk’s perspective on free expression has sparked widespread debate internationally. Although he has advocated for minimal censorship, he has conveyed that his interpretation of free speech corresponds with the laws of individual nations. Yet, the current situation in Brazil has put this principle to the test, as Musk’s enterprises find themselves in conflict with the Brazilian judicial framework.

#### Starlink’s Rebellion and Legal Strategies

Starlink, a division of Musk’s SpaceX, holds a significant foothold in Brazil, serving approximately 250,000 customers. The company was instructed by Brazil’s highest court to prevent access to X, following the platform’s inability to establish a local legal representative, a stipulation under Brazilian regulations. The court also levied fines on X, which have reportedly surpassed $3 million.

In retaliation, Starlink declared that it would not follow the directive until Brazilian officials unblocked its frozen assets. The firm contended that the court’s move to freeze its assets was unconstitutional and deprived it of due process. This refusal to restrict X appears to be a tactical strategy by Starlink to compel the Brazilian government to unfreeze its finances.

On social media, Musk intensified the situation by threatening reciprocal measures against the Brazilian government. He asserted that unless the confiscated assets of X and SpaceX were restored, his companies would pursue the seizure of government possessions in retribution.

#### The Influence of Judge Alexandre de Moraes

Judge Alexandre de Moraes, who enacted the order to suspend X, has been a contentious figure in Brazil. Recognized for his assertive stance on social media regulation, de Moraes has undertaken measures that some perceive as infringing on free speech. He has imprisoned individuals without trial for making threats online, sentenced a sitting congressman to nearly nine years for threatening the court, and authorized raids on entrepreneurs with scant evidence.

De Moraes’ actions have ignited discussions about the balance between ensuring public order and protecting free expression. His determination to block X was predicated on the platform’s refusal to conform to Brazilian laws, specifically its failure to designate a local legal representative. The judge contended that this was vital for maintaining accountability and adherence to local regulations.

However, X has countered these assertions, claiming that de Moraes’ requests were unlawful and politically driven. The platform’s Global Government Affairs account accused the judge of targeting X due to its refusal to censor his political adversaries. The account further claimed that de Moraes threatened to incarcerate X’s Brazilian legal representative, which prompted her resignation and the freezing of her bank accounts.

#### Public Response and Consequences

The court’s ruling to block X and the ensuing actions by Starlink have ignited widespread discussion in Brazil. Many citizens condemned the initial decision to prohibit VPN services, which would have hindered users from bypassing the restrictions on X. This backlash led de Moraes to revise his order, permitting VPN applications to remain accessible in app stores.

The unfolding scenario has also prompted considerations regarding the involvement of international tech firms within local legal frameworks. Musk’s refusal to abide by Brazilian law, combined with his reciprocal threat assertions, could establish a precedent for how global tech behemoths might confront legal obstacles in different nations.

#### Conclusion

The protracted contention between Elon Musk’s Starlink and the Brazilian judiciary underscores the intricate dynamics between global tech enterprises and national legal systems. As Musk persists in advocating his interpretation of free speech, his companies are increasingly clashing with local laws. The resolution of this standoff may yield significant repercussions, both for Musk’s initiatives in Brazil and for the broader connection between tech titans and governments worldwide.

As the legal conflict progresses, it remains uncertain how both factions will navigate this critical confrontation. Will Starlink’s resistance foster a solution, or will it exacerbate tensions between Musk and the Brazilian administration? The world is attentively observing as this unparalleled situation unfolds.

Starliner Spacecraft’s Speaker Produced Uncommon Sonar Sounds on Saturday

### A Space Enigma: Unexplained Sounds Emerge from Boeing’s Starliner Docked at the ISS

On an ostensibly ordinary Saturday aboard the International Space Station (ISS), NASA astronaut Butch Wilmore stumbled upon an unforeseen auditory phenomenon within Boeing’s Starliner spacecraft. The vehicle, which has been moored at the ISS for almost three months, produced a peculiar sound that Wilmore characterized as a “pulsing noise, akin to a sonar ping.”

### The Event

The situation arose when Wilmore detected the atypical sound emanating from a speaker within the Starliner. He quickly communicated with Mission Control at NASA’s Johnson Space Center in Houston to report the anomaly. “I’ve got a question about Starliner,” Wilmore stated. “There’s an unusual noise coming through the speaker … I’m uncertain of its origin.”

Wilmore conjectured that the sound could be related to some anomaly in the connection between the ISS and the spacecraft. He asked the flight controllers in Houston to listen to the audio from Starliner to assist in diagnosing the matter. Mission Control rapidly established a “hardline” connection to monitor the audio feed from the spacecraft.

As Wilmore positioned his microphone near the speaker, the notable sonar-like ping was recorded and sent back to Earth. “Alright Butch, that one came through,” Mission Control affirmed. “It was somewhat like a pulsing noise, resembling a sonar ping.”

Wilmore reiterated the procedure, allowing the flight controllers to hear the noise again before leaving the investigation in their hands. “Alright, over to you. Contact us if you find out what’s going on,” he noted.

### A Space Enigma

The odd sound was documented and shared by Rob Dale, a meteorologist from Michigan, who uploaded it online. The recording has since ignited curiosity and theories, as the origin of the sound remains unknown.

In space, astronauts sometimes experience bizarre phenomena that are hard to explain. For example, during China’s inaugural human spaceflight in 2003, astronaut Yang Liwei reported a noise reminiscent of an iron bucket being struck by a wooden mallet while in orbit. Scientists later linked this noise to minor deformations in the spacecraft resulting from pressure differentials between its inner and outer walls.

While the sonar-like sound in Starliner is likely to have a harmless explanation, it is significant given the string of difficulties Boeing and NASA have encountered with the spacecraft. These challenges encompass substantial helium leaks during flight and malfunctioning thrusters, which have sparked concerns regarding the spacecraft’s dependability.

### The Path Forward for Starliner

Despite these concerns, NASA and Boeing are advancing with plans to return Starliner to Earth. Initially, the spacecraft was intended to bring back its crew, including Wilmore and fellow astronaut Suni Williams. However, due to the ongoing uncertainties surrounding Starliner’s functionality, NASA opted to bring the spacecraft home autonomously.

Starliner is now set to return to Earth on Friday, September 6, 2024. Meanwhile, Wilmore and Williams are projected to come back to Earth in February 2025 aboard a Crew Dragon spacecraft, which is slated for launch with just two astronauts later this month.

### Conclusion

The enigmatic noise within Starliner adds yet another layer of fascination to the ongoing tale of Boeing’s beleaguered spacecraft. While the sound is likely inconsequential, it serves as a reminder of the intricacies and unpredictabilities in space exploration. As Starliner gears up for its autonomous return to Earth, all eyes will be on Boeing and NASA to observe how they tackle the challenges ahead and ensure the spacecraft’s safe return.

### The Enigmatic Comeback of Agatha Harkness: What to Anticipate from *Agatha All Along*

Marvel Studios has once again enchanted fans with the highly awaited arrival of *Agatha All Along*, a spinoff series stemming from the critically acclaimed *WandaVision*. Set to debut on Disney+ on September 18, 2024, this series is expected to explore the enchanting realm of witches within the Marvel Cinematic Universe (MCU). With Kathryn Hahn returning in her role as the mysterious Agatha Harkness, the show is set to be a thrilling, magical expedition that enthusiasts will not want to overlook.

#### A Quick Overview: Who is Agatha Harkness?

For those needing a reminder, Agatha Harkness was first seen in *WandaVision* as the seemingly inquisitive neighbor, Agnes. However, it was later unveiled that she was, in fact, Agatha Harkness, a formidable witch with a shadowy history. Agatha’s primary ambition was to seize Wanda Maximoff’s (known as Scarlet Witch) chaos magic, but she ultimately faced defeat and became ensnared in her Agnes identity by Wanda.

Agatha’s character swiftly gained a fervent following, largely due to Kathryn Hahn’s enthralling portrayal and the infectious “Agatha All Along” tune that became a sensation. The rising popularity of the character paved the way for this spinoff series, which intends to uncover Agatha’s fate post-*WandaVision*.

#### The Narrative: A Trek Through the Witches’ Path

*Agatha All Along* resumes from where *WandaVision* concluded, with Agatha devoid of her powers and confined in her Agnes guise. However, the series shifts gears when a mysterious goth teenager assists in freeing Agatha from her enchantment. This teenager, revealed to be named Billy, implores Agatha to accompany him on the famed Witches’ Road—a mystical gauntlet filled with challenges that promises a witch the return of what they lack, should they prevail.

Enticed by the chance to restore her powers, Agatha consents to lead Billy down the Witches’ Road. Along their journey, they gather a desperate group of witches, each possessing distinct talents and stories. Together, they embark on a treacherous adventure that will push their boundaries and unveil dark truths from Agatha’s history.

#### The Cast: A Coven of Mighty Witches

The series features a striking ensemble cast, with numerous familiar faces reprising their roles from *WandaVision*. In addition to Kathryn Hahn as Agatha Harkness, the lineup includes:

– **Aubrey Plaza** as Rio Vidal, a warrior witch with a concealed past.
– **Joe Locke** as Billy, the teenage familiar who might have a deeper bond with Wanda Maximoff.
– **Patti LuPone** as Lilia Calderu, a 450-year-old Sicilian witch with ancient wisdom.
– **Sasheer Zamata** as Jennifer Kale, a sorceress linked to the magical forces of the Marvel Universe.
– **Ali Ahn** as Alice, a witch with her own ulterior motives.
– **Miles Gutierrez-Riley** as Billy’s boyfriend, whose significance in the tale remains enigmatic.

Moreover, several actors from *WandaVision* will reprise their roles, including Debra Jo Rupp as Sharon Davis (aka “Mrs. Hart”), Emma Caulfield Ford as Sarah Proctor (aka “Dottie Jones”), and David Payton as John Collins (aka “Herb”). These characters will now become part of Agatha’s coven, enriching the narrative.

#### Theories and Speculations: Who is Billy?

One of the most fascinating facets of the series is the identity of Billy, the teenager who liberates Agatha from her enchantment. Fans have been theorizing that Billy might be Billy Kaplan, also recognized as Wiccan, one of Wanda Maximoff’s twin sons in the comics. In *WandaVision*, Wanda’s twin sons, Billy and Tommy, were conjured as part of her reality-altering spell but ceased to exist once the spell was reversed.

However, in the comics, Billy and Tommy eventually returned to existence, with Billy evolving into Wiccan, a powerful young sorcerer and a member of the Young Avengers. The teaser for *Agatha All Along* suggests a possible link between Billy and Wanda, featuring a magical script resembling an ornate “M” (or perhaps a “W” and “V”) surfacing when Billy attempts to unveil his identity. This has ignited speculation among fans that Billy could indeed be the forthcoming Wiccan, potentially paving the way for the introduction of the Young Avengers in the MCU.

#### A Sinister and Spooky Quest

*Agatha All Along* promises to deliver a sinister, spooky experience that plunges into the mystical and supernatural
